Principal Electrical and Firmware Systems Architect

Join our fast-paced and passionate Systems Engineering, Integration, and Test team as a Principal Electrical and Firmware Systems Architect. You will own the electrical and firmware architecture of our laser and photonic systems, translating system-level photonic requirements into clear, testable requirements for every electrical and firmware element of the system, from communications and electronics infrastructure to analog signal processing, FPGA, and frequency-locking servo control.

This is a dynamic, hands-on role for a self-starter who thrives in a fluid startup environment. You'll work on cutting-edge technologies, work closely with leadership, and build the engineering practices that support our mission and growth. Your key responsibilities are as follows:

• Partner with the Photonic Systems Architect to decompose and flow down system requirements into electrical and firmware requirements, specifications, and acceptance criteria.
• Define the system communications topology and architecture, including internal buses, controller hierarchy, external interfaces, timing, and data flow between subsystems and the host software.
• Architect analog signal processing and control chains, including photodetection, signal conditioning, low-noise amplification, and data conversion, and own the associated noise and bandwidth budgets.
• Define FPGA architecture and partitioning between FPGA, microcontroller, and host processing, including real-time control, data acquisition, and digital signal processing functions.
• Architect frequency-locking and servo control systems for laser stabilization, including error-signal generation, loop design, bandwidth and stability analysis, and lock acquisition and recovery.
• Define the electronics infrastructure, including power distribution, grounding, shielding, thermal management, cabling, and board and chassis-level partitioning.
• Define and control electrical and firmware interfaces through interface control documents (ICDs), working directly with the photonics, mechanical, and software teams.
• Develop integration and verification strategies, including test plans, requirements traceability, and system-level characterization on real hardware.
• Lead system-level troubleshooting across the optical/electrical/firmware boundary, and drive root cause analysis and corrective action.
• Present and defend electrical and firmware architecture and maturity at technical reviews (SRR, PDR, CDR) to leadership and customers.
• Drive design for manufacturability, testability, and reliability to support scalable production.
• Mentor engineers and build a culture of technical rigor, ownership, and cross-functional collaboration.
